Crop Rotation Promotes Garden Efficiency

Squash eventually depletes particular soil nutrients.

Maya Angelou likely enjoyed gardening. She said, “In diversity there is beauty and there is strength”. That is how the healthiest of ecosystems, including home gardens, function. Vegetable gardens are generally diverse. However, each group of a particular vegetable is rather homogenous. Crop rotation can compensate with diversity through the seasons.

Crop rotation is growing different vegetables in particular places from season to season. It is the same as growing particular vegetables in different places from season to season. Distinctly consumptive vegetable plants should relocate each season. Less consumptive sorts may perform adequately in the same place for years. Diversity makes it interesting.

Each type of vegetable plant consumes particular nutrients from the soil. Eventually, they can deplete their soil of these particular nutrients. Crop rotation allows them to utilize the nutrients they need from undepleted soil instead. Meanwhile, other vegetable plants can grow in the vacated soil. These different types of plants utilize different types of nutrients.

For example, tomato plants notoriously deplete the soil of particular nutrients. Corn does the same. However, each depletes different nutrients. Therefore, corn can be satisfied in soil vacated by tomato plants. Likewise, tomato plants can be satisfied in soil vacated by corn. Furthermore, each promotes the restoration of the soil nutrients needed by the next.

Crop rotation also disrupts proliferation of several pathogens that infest vegetable plants. Dormant spores of bean rust disease overwinter in the soil beneath infested bean plants. They efficiently infest any receptive bean plants to occupy the soil during the next spring. However, they can not infest plants that are not related to beans, such as pepper or okra.

Summer vegetables should be situated accordingly as they return to vegetable gardens. Tomato, pepper and eggplants are related, so should not grow where any grew last year. The same applies to bean and pea. Squash and cucumber are related also, but are less consumptive. They may perform adequately within the same soil for more than one year. Several summer and winter vegetables are related.

Rotation Improves Vegetable Garden Production

Summer squash are consumptive vegetables.

Vegetable plants are mostly unnaturally productive. Extensive breeding compels them to yield fruits and vegetative parts that are bigger, better and more abundant that what their ancestors produced. Increased production increases their reliance on resources. Without crop rotation, some sorts of vegetable plants noticeably deplete some of what they need. 

Rotation, which is the same as crop rotation or garden rotation, is a technique of growing vegetables where different types of vegetables grew previously. In other words, one type of vegetable does not grow in any one place for too long. Some vegetables may produce well in some types of soil for a few years. More consumptive types prefer annual rotation. 

This technique disrupts the depletion of particular nutrients that particular types of plants crave. It also allows for replenishment of depleted nutrients in the absences of plants that cause such depletion. Furthermore, some soil borne pathogens find this active cycling to be disruptive. Eventually, plants that cycled out can cycle back into a particular situation.

Tomato plants are particularly consumptive, so appreciate rotation in many types of soils. Eggplant and pepper are related to tomato, so crave many of the same resources, even if they are less consumptive. Therefore, they should not cycle directly into soil relinquished by tomatoes. Unrelated vegetables, such as squash, corn or bean, are more appropriate. 

Warm season vegetables that are now returning to the garden might appreciate rotation. A bit of research to determine appropriate placement for them may significantly enhance production. It helps to know which vegetables are related, such as mustard, collard, kale, radish and turnip (of Cruciferae Family), or squash and melon (of Cucubitaceae Family).

Because corn is so high, it should grow to the north of a vegetable garden. Unfortunately, rotation may dictate that it grows to the east for a while, or only in portions of the northern edge that it avoided for a while. Pole beans that like to climb wire fences may sometimes need reassignment to different portions of their fence. Peas should follow their example since they are related.

Garden Rotation Shares The Goodies

Beans produce better in new territory.

Certain parts of the vegetable garden are ideal for certain types of vegetables. Wire fences are perfect for pole beans to climb. Corn belongs at the northern edge where it will not shade lower plants. Vegetable gardening would be simpler if it were like permanent landscaping. Instead, vegetable plants are seasonal and very consumptive. They prefer fresh resources. Garden rotation gives them more of what they crave.

Garden rotation, or crop rotation, is growing vegetables where they have not grown recently. For the most efficiently planned gardens, it happens seasonally. Alternatively, some types of vegetables might be happy to grow repeatedly in the same soil for a few years. Some vegetable plants are more consumptive than others. Some soils are more susceptible to nutrient depletion than others. A few variables are involved.

Furthermore, the various vegetable plants deplete distinct sets of nutrients. Conversely, they allow other nutrients to replenish. That is why garden rotation is so effective. For example, if beans grow in the same location for too long, they deplete their favorite nutrients. The nutrients that they use less of secretly replenish. Tomatoes or corn might appreciate the replenishment, without craving so much of what is deficient.

Eventually, vegetable plants can return to a location where they grew a few years earlier. Again, a few variables are involved. Some might return after an absence of only a single year. Consumptive plants, such as tomatoes and beans, should avoid a previously used location for three or more years. So should related vegetables. Peppers and eggplants are related to tomatoes, so should avoid the same used locations.

Garden rotation can also inhibit proliferation of some soil borne pathogens. In other regions, this is a more serious concern. Soil borne pathogens that infest mildly during their first year might flourish with the same host material during a second year. Garden rotation deprives them of that.

Crop Rotation For Home Gardens

00325thumb
Pepper plants should get relocated annually.

Vegetable gardening is not permanent landscaping. With few exceptions, vegetable plants are annuals, like bedding plants. They do their respective jobs within only a few months. When finished, they relinquish their space to different vegetable plants of a different season. More of the same will be in season again in a few months. Crop rotation is something to consider when that happens.

Crop rotation is standard procedure for field crops involving several acres of the same variety of vegetable. Some crops grow on the same land for a few years. Some change annually. With few exceptions of big perennial vegetable plants, none stay in the same location for too long. Some fields go fallow for a season without production. Most simply produce a different type of vegetable.

Vegetables that grow for too long in the same soil eventually deplete some of the nutrients that they use most. Different types of vegetables deplete different types of nutrients. Crop rotation allows soil that was depleted by one type of vegetable to be used by another type that does not mind the depletion. While slowly depleted of a new set of nutrients, soil recovers from previous depletion.

For example, a sunny side of a fence is an ideal spot to grow pole beans. It is tempting to grow them there annually. However, they do not perform as well for a second season, and are likely to be scant for a third year. However, tomatoes appreciate what beans do to the soil, and do not miss what they took from it. After tomatoes take what they want for a season, beans are ready to return.

Crop rotation also helps to disrupt the proliferation of host-specific pathogens that overwinter in the soil and decomposing plant parts.

Generally, new vegetable plants should not be of the same family as vegetable plants that they replace in a particular location. Beans, squash, okra or corn should be happy where tomatoes grew last year. Peppers and eggplants are of the same plant family as tomatoes, so are likely to crave what the tomatoes already depleted. They are also susceptible to some of the same pathogens.

Crop Rotation Improves Vegetable Production

90327thumbA south or west facing fence is a perfect place to grow pole beans. Twine can be strung in a zig-zag pattern between single rows of partly protruding nails along the top and bottom. The spacing of the nails should match that of the pole bean plants. Bean seed sown at the base of the fence germinate and grow quickly. Vines are happy to cling to the string and climb to the top of the fence.

Alas, it is temporary. Pole beans are annuals. They start to grow now, produce all summer, and then yellow and ultimately die by autumn, leaving the fence bare again. If the technique is repeated in the same spot with the same sort of pole beans the following spring and summer, the plants could be noticeably less vigorous. Repeating if for a third season could be downright disappointing.

It is best to grow beans in a different location every year if possible. After a few years, they can return to the same fence. Until then, tall plants, like caged tomatoes or corn, can be cycled through the area in front of the fence. Tomatoes and corn also perform better if not grown in the same spots for more than one season at a time. This process of cycling crops is known as ‘crop rotation’.

Soil borne pathogens proliferate along with the host plants that sustain them. Such pathogens may not be a noticeable problem in the first year while they get established. However, they are likely to be established and ready to infest the same sorts of host plants more aggressively in a subsequent season. Crop rotation of the host plants to cleaner locations annually interrupts this process.

In local soils, crop rotation is likely more important to compensate for nutrient depletion. Tomatoes are greedy with particular nutrients that other vegetable plants may not need in such quantities. The same applies to other vegetable plants. Tomatoes planted where other tomatoes grew last year may notice a lack of the nutrients that they crave the most of. However, zucchini may not miss what the tomatoes of last year took. Conversely, tomatoes may not notice what may be lacking where zucchini or other vegetables grew last year.
